If this step fails, I recommend running the following command to capture all screen output to /tmp/yum_upgrade.

# yum upgrade 2>&1 | tee /tmp/yum_upgrade

Failures generally indicate that a currently-installed RPM has a dependency that cannot be satisfied with packages from the new Fedora Core release. Deprecated packages and packages from third party repositories may cause this problem.

The following generates a list of packages that may need to be removed prior to a successful yum upgrade.$ perl -ne 'print "$1\n" if ((/Error: Missing Dependency:.*is needed by package (.*)$/) || (/Error: Package (.*?) needs.*, this is not available./))' /tmp/yum_upgrade | sort | uniq

If the initscripts package is returned, I recommend booting into the latest Fedora Core 4 kernel, removing all previous kernels, and running yum upgrade again.
